Banks are a really interesting idea that I honestly, hadn't even considered yet. The more I ponder it though, the more fun it sounds to implement; especially with the new procedurally generated towns that I am working on at the moment...

What exactly do you have in mind for character customization? With that in mind, I am adding the ability for players to earn titles in the next release.

Further mini-map enhancements are coming. I have planned to add resource layers for some time, but haven't gotten around to it yet. I'll add this to the feature road map so I don't lose sight of it again.

Hah! I could add a sword that doubles as a light source that way you wouldn't have to always have candles on your hotbar...

There are craft-able teleporters in game already, but getting back to the proc gen towns that I am currently working on, some sort of inter-settlement travel would be cool...

Guilds are definitely something that I have been wanting to add for awhile. Nice to see someone else that thinks they'd be cool. I'll add this one to the feature roadmap as well.
